I too had started this engine in 2008 and let it sit in my shop for maybe seven years or so while I built many other models. I finally picked it up again last summer after visiting the Finger Lakes Live Steamers and Steam Town in scranton, Pa. I took advantage of the stay at home orders and got it running on air. I am now designing the boiler and using many resources from these sites and steam clubs like The Cinder Sniffers. I have read many build logs, yours included KVOM, and learned much. I just got the Australian model steel boiler code and started reading up. I have seen these boilers built many ways right down to one with 1/4” thick tube sheets and only 3/16” plates. Can I ask you KVOM for some insight to your build? I have a few questions and would love to share my knowledge and experience so far. Heres apic or two.
